Abstract
A method for inspecting blade tip clearance between at least one rotor blade and a case spaced radially outward from the rotor blade is provided. The method includes inserting a probe into an aperture defined in the case and emitting electromagnetic energy into the case using the probe. The method also includes detecting electromagnetic energy reflected from a blade tip portion of the rotor blade and determining a blade tip clearance defined between the blade tip and the case based on the detected electromagnetic energy.
